地下水出流单断沙关系的回归分析

Regression Analysis of Index and Cross-Section Average Sediment Concentration Relation of Groundwater Outflow

阐述回归分析理论,根据南洞口站8年的实测输沙率成果资料作回归分析,从而了解和认识地下水出流的泥沙在横向和垂向上的分布规律及各垂线单沙与断沙之间的相关系数、回归效果、回归误差的多少。掌握泥沙的变化规律,对该地区的工、农业用水,城市用水,水资源的合理化利用和保护有着十分重要的意义。

This paper made a regression analysis according to 8-year observed sediment discharge data from Nandongkou Hydrometric Station, so as to understand the interrelationship, regression effects and the regression error of the index and crosssection average sediment concentration of the groundwater outflow. The results could be used to analyze the law of sediment change, which is important for utilizing and protecting the local water resources.
